SKATE.

, Application filed June'6, 1917. Serial No. 173,088.

highgrade steel, has come intovery general use, but difficulty has been experienced in. that the thin blade dulls very quickly. Thus,

in a race, if the skater should happen to pass a gritty spot on the ice, the skate would immediately be rendered unfit for further use and he would be compelled to change, and this necessitates the keeping of several pairs of skates on hand, constituting a considerable expense. Furthermore, when a change is made, it is often impossible to reproduce the same conditions to which the skater had gotten accustomed to and this slight change may be sufficient to throw the skater ofl? his best stride. I

My invention has for its principal object to provide a tubular skate, with an interchangeable blade, so that with one pair of frames any number of blades may be used,

and as soon as one blade or set of blades have become dull, they may be removed and others quickly set in place. This makes it also possible to change the style of blade without detaching the frame from the shoe.

The improved construction will be clearly understood from the following detailed description and the features of novelty will be particularly pointed out in the claims.

Referring to the drawing illustrating the invention, 7

Figure 1 is an elevation of my tubular skate embodying my invention, the broken lines indicating a blade of different type which may be quickly attached.

Fig. 2 is a fragmentalsectional elevation illustrating the interlocking engagement between the blade and socket.

Figs. 3, 4 and 5 are respectively cross secthereon respectively the heel and toe plates 14 and 15, to which is attached the shoe 16. The tube 10 has the depending spaced flanges 17 between which is riveted by suitable rivets 18, the plate 19. The latter forms a spacing device between the two flanges 17 and forms a socket in which the blade 20 may be inserted" and secured. I

To firmly hold the'blade in place, I stamp or otherwise form the plate 19 with a number of substantially hooked portions 21 spaced alongthe lower edge of the plate,

leaving a plurality of recesses or sockets22.

The blade 20 is formed with similar hooked portions 23 of a size such as to readily pass into the sockets 22 and of a shape to interlock with the hooks 21. Thus, when the blade is to be inserted, the hooks 23' are fitted into the recesses 22, and the entire blade shoved backward so as to secure an interlocking engagement with the hooks 21, as clearly appears in Fig. 2. It will be noted that the hooks 23 and 21 are of such relative size as to completely fill up the space in a vertical direction, and thus provide a firm grip between the parts.

After the blade has been inserted, it islocked in position by suitable means such as a spring pin 2 L which passes through registering apertures formed in the blade and flanges of the tube.

vide between the spacing and locking plate 19 and the adjacent flanges 17, facing plates 25 made of steel or some similar metal, so as to reinforce the flanges 17 of the tube. It will be understood that the latter is usually of aluminum or some similar light metal. The material of plates 25 may be chosen particularly for its wear resisting qualities and toughness. I

When the skater desires to change a blade,

he merely removes the spring pin 24 and pulls forward the blade 20 until the hooks 23 are entirely disengaged and then removes the blade by passing the hooks through the recesses 22. Should there be a tendency for ice the blade to stick, a slight tap on the rear 7 end will suffice to free the same.

Although I have described one embodiment of the invention, it will be understood that various modifications may be .made within the skill of a mechanic without departing from the spirit of the invention and the scope of the appended claims.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent is:

1. A convertible skate comprising a horizontal tubular frame member having an opening at the bottom thereof, a plate having a plurality of hooked portions disposed in said opening, a blade having corresponding hooked portions adapted to engage with said first mentioned hooked portions, and means for locking the blade to the tubular member when the hooked portions are interengaged.

A convertible skate comprising a horizontal tubular frame member having downwardly extending flanges, a plate having a plurality of hooks riveted between said flanges, there being recesses between said hooks, a blade having corresponding hooked portions adapted to pass through said recesses to interengage with said first mentioned hook portions, and means for locking the blade to the frame when the hooks are interengaged.

3. A convertible skate comprising a tubular frame member having downwardly disposed flanges, a pair of facing plates and an intermediate spacing plate between said flanges, said spacing plate being formed with a plurality of hooked portions, a blade having corresponding hooked portions adapted to pass into said recesses and to engage with said first mentioned hooked portions, and means for locking the blade to the frame when the hooked portions are in engagement.

Signed at New York city, in the county of New York and State of New York, this 25th day of April, A. D. 1917.
